Hi David It's hard to say with so little information what could be wrong, and I have not seen any response yet, so I thought I could give you something that might help you. I've done a video about setting up the Ceph, Grafana, and Prometheus triangle from scratch, the components responsible for hardware metrics and monitoring. Maybe that could help? https://youtu.be/c8R64LF3JjU And I've also done a separate video about disk prediction and smart data in a Ceph cluster that could give you some insights. https://youtu.be/KFBuqTyxalM I hope this helps.
